We recommended that customers use a PlainTalk microphone connected directly to the Macintosh 630 family computer instead of the built-in microphone on the AudioVision 14 Display. As an alternative, disabling the ~AudioVision control panel may improve the recording quality of the AudioVision 14 microphone.
The following computers are in the Macintosh 630 family: LC 630, Quadra 630, Performa 630, Performa 635, Performa 636, Performa 637, and Performa 638.
